Overview
Ventricular tachycardia can cause life-threatening or fatal hemodynamic compromise or it can degenerate into a life-threatening rhythm called ventricular fibrillation. In general, supraventricular tachycardia with aberrancy is generally better tolerated and is not necessarily a medical emergency. Common complications of ventricular tachycardia include sudden cardiac death, cardiomyopathy, V-fib, and infection related to ICD. Prognosis of ventricular tachycardia in patients largely depends upon the presence and severity of underlying cardiac disease.
Natural History
Ventricular tachycardia can cause life-threatening or fatal hemodynamic compromise or it can degenerate into a life-threatening rhythm called ventricular fibrillation. In general, supraventricular tachycardia with aberrancy is generally better tolerated and is not necessarily a medical emergency. An exception is if the the wide complex tachycardia is due to atrial fibrillation conducting down a bypass track such as is seen in Wolff-Parkinson-White syndrome (WPW) in which case the rhythm can degenerate into life-threatening ventricular fibrillation.
Complications
Common complications of ventricular tachycardia include:[1]
- Sudden cardiac death
- Cardiomyopathy
- Infection related to implantable cardioverter defibrillator
- V-Fib
Prognosis
- Prognosis of ventricular tachycardia in patients largely depends upon the presence and severity of underlying cardiac disease.[2][3]
- In patients without evidence of ischemia or structural heart disease, prognosis is generally good.
- Meanwhile, patients with underlying cardiac pathology may require lifelong medical therapy with medications, catheter ablation, and/or implantable cardioverter defibrillator (ICD) placement.
